Apple today shared two new videos on its YouTube channel, again designed to promote the Portrait Mode feature that’s unique to the dual-camera iPhone 7 Plus.

Both videos are 15 seconds in length and show the Portrait Mode in action, with an explanation on how it blurs out the background for better portrait shots of people.

Portrait Mode, introduced in iOS 10.1, uses a shallow depth-of-field effect to make portrait photos “pop,” mimicking the results that can normally only be obtained with a high-end DSLR and a telephoto lens. Portrait Mode uses the 56mm lens included in the iPhone 7 Plus, with Apple’s image signal processor working to scan a scene to recognize people and other objects to separate the foreground from the background for the blurring effect.

Today’s ads follow two similar ads that were released earlier this week, also designed to show off Portrait Mode on the iPhone 7 Plus.
